Mailbox Books was founded by Ed Zolna; he retired in 1998 and sold part of the company's assets to Sean Rabbitt.[1] Sean later changed the name to Rabbit Valley due to another company suing him for the rights to the "Mailbox Books" trademark.[1][2][3][4]

Rabbit Valley Comic Store was the first large online store to cater to furries. Today it remains a staple of the commercial aspect of the fandom and continues to help distribute the work of new and upcoming artists as well as sell some of the most popular titles in the fandom.

Rabbit Valley also used the name Rabco Publishing Inc., but reincorporated as Rabbit Valley Inc. in 2004.
